Routine Maintenance
When Printing Becomes Faint or Colors Are Incorrect
When printing becomes faint or colors are incorrect even if ink remains in the ink tanks, the print
head nozzles are probably clogged. Print the nozzle check pattern to confirm the condition of the
nozzles and then perform Print Head Cleaning.
If print results are not satisfactory, performing Print Head Alignment may improve print quality.
